LGCM modules are the analog line gateways for the LIK/UCP systems. Not sure but I think some of these have a common point of failure in the power supply section of the gateway board. I'd like to get these things fixed instead of just junking them. I've fixed LDK power supplies, and they seem to blow their power supply caps, and replaced the batteries on the LDK motherboards but not sure what's up with these gateways. I'm sure someone somewhere has fixed these.
